  • Components such as solar modules 32 may be mounted to the curved mounting surface 30 of the mounting rack 20 using movable mounting clips 21. Due to the curved mounting surface 30 of the mounting rack 20, the weight of the solar modules or other components 32 mounted onto the mounting surface 30 is naturally shifted toward the pivot axis 34 that runs through the torsion beam 14. In other words, the curved mounting surface 30 of the mounting rack 20 advantageously moves the center of gravity of the mounting assembly 10 closer to the pivot axis 34 in the torsion beam 14, which results in less overhung weight in the mounting assembly 10. This balances the weight of the modules 32 more evenly over the rotating torsion beam 14 and results in less force required to rotate the mounting assembly or solar tracker 10.

  • the curved mounting surface 30 of the mounting rack 20 advantageously balances the weight of the solar modules 32.
  • This balanced configuration can be achieved when the weight X distance of the front of the mounting rack 20 is equal to the weight X distance of the rear of the mounting rack, about the balance axis 36. More particularly, the system is in balance when a first portion of the weight of the solar modules 32 or other mounted components above the balance axis 36 multiplied by the first distance 38 is substantially equal to a second portion of the weight of the solar modules 32 below the balance axis multiplied by the second distance 40.
  • the first and second distances 38, 40 can be measured at different locations and multiple points along the solar modules 32 and along the front and rear surfaces 30, 28 of the mounting rack 20. Perfect balance is achieved in the mounting assembly 10 when:
  • n represents the number of components in the mounting assembly
  • m represents that mass of each component
  • d is the distance vector from the center of the tube to the center of gravity of each component.
  • Another advantage derived by reducing the overhung weight of the array of solar modules 32 is that the natural resonant frequency of the solar tracker 10 is increased, thereby minimizing structural material required in the design.
  • a higher resonant frequency keeps the solar tracker 10 from coupling into the wind and experiencing high dynamic loads.
  • Dynamic loading can be extremely detrimental to the structural integrity of a tracking system. It is extremely important to minimize and eliminate dynamic loading in tracking system design.
  • the curved mounting surface 30 of the mounting rack 20 balances the weight about the pivot axis 34 better, which increases the natural resonant frequency of the structure, thereby allowing less expensive structural designs. Less structural material equates to less cost. Minimizing material usage in a photovoltaic system also realizes earlier energy payback on the system.
  • the inherent stiffness of the curved front frame support 22 of the mounting rack 20 also results in minimization of material.
  • the curved design of the mounting rack 20 also minimizes material necessary in the structure by drawing from the inherent structural stiffness of the arch. This design achieves higher strength and stiffness over a straight structural member since it directs some of the force into compression and tension instead of all the forces being directed into a bending moment.
  • PV modules may perform slightly better when off track to the sun by a small amount.
  • the mounting surface 30 of the mounting rack 20 is curved, the modules will not all be on a single plane and therefore cannot all be perpendicular to the sun's rays during tracking.
  • the area exposed to the sun can be calculated as the cosine of the off track angle.
  • the area reduction effect of this gently curved surface is generally minimal.
  • some thin film PV modules perform better when slightly off track to the sun. When this is the case, the curved mounting surface 30 of the mounting rack 20 may result in a higher output over a flat rack.
  • the user may reduce the torque load of exemplary solar trackers 10 by mounting solar modules 32 to the curved mounting surface 30 of the mounting rack 20. This will shift the load or weight of the solar modules 32 toward the pivot axis 34 in the torsion beam 14, thereby reducing the torque load about the pivot axis 34. More particularly, the load of the solar modules 32 is shifted such that the center of gravity of the mounting rack 20 and the modules 32 is at or near the pivot axis 34.
  • the user may balance the solar tracker 10 by rotating the mounting rack 20 such that a first portion of the weight of the solar modules 32 above the balance axis 36 multiplied by the first distance 38 is substantially equal to a second portion of the weight of the solar modules 32 below the balance axis multiplied by the second distance 40.
  • the first distance 38 is the distance between the balance axis 36 and the curved mounting surface 30 of the mounting rack 20
  • the second distance 40 is the distance between the balance axis 36 and the rear surface 28 of the mounting rack 20. This can reduce the effort or torque required to rotate the array of solar modules 32 during tracking dramatically, even close to zero.
  • the solar tracker 10 may be rotated 42 to track the sun.
